Development of Integrated Detection System for Shock Vibration by using MEMS Accelerometer

In this paper an integrated system is developed to detect shock vibration by using MEMS accelerometer. The interface circuit which converts the signal from an accelerometer capacitive element to a pulse signal for digital signal processing is built. Changes in the capacitance between fixed and movable plates are induced by acceleration from shock vibration. Interface circuit incorporating this capacitor then extracts the acceleration signal and converts it to digital or analog form using microcontroller microprocessor. GUI is developed to make the integration data system more interesting and user friendly. The sensing of MEMS and monitoring software are integrated together to provide real time acquire data and graphical visualization for monitoring, recording and analysis purposes.
